Letters Patent No. 108,959, dated November 8, 1870.

IMPROVEMENT IN SUOKER-ROD COUPLINGS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern.'-

Be it known that I, JAMES H. Baarn', of Franklin, in the countyvof Venango and State of PennsylvVania, have invented a new and useful Improvement in Sucker-rod J oint-Ooupling; and I do hereby declare that the following is a full, clear, and exact description thereof', which will enable others skilled in thcv art to make and use thcsame, reference being had to the accompanying drawing forming part 4of this specification.

This invention relates to a new and useful improvement in a coupling for the joints of sucker or pumprods, whereby the joint is made durable and effective, is easily-applied, and readily detached; and

It consists in a slotted sleeve-coupling, with elastic ends, secured on the rod, as hereinafter more fully described.

In the accompanying drawing- Figure 1 represents a longitudinal view of the coup-` lin place when the rod is in use.

from near the center, dividing the ends, from points.

C, int-o four (more or less) parts, which, by reason of such separation, are made elastic, so that they may be contracted or brought together by means of a nut or K otherwise, and made to embrace the rod, as seen in the drawing.

Near the ends of thc coupling, on thcinncr side, there are shoulders, as seen at D; and on the parts of the rod, as seen at E, there are corresponding shohly ders.

Whenl the ends of the coupling are contracted, as seen in the drawing, these shoulders D, and E engage with each other, and prevent the parts ofthe rod from being drawn asunder, while either part of the rod may turn or revolve, if desired.

. In this example of my invention, two methods are shown for' contracting and holdingthe ends of the coupling around the parts ofthe rod.

One is by a screw-nut, 1*,Which engages with a screw-tlu'ead on one end of the coupling.

' The other method is a sliding band, G, with a lug on its inner side, as seen at H, fig. 2, which engages with a notch in the coupling, as seen at L There is a series of these notches or recesses open ing into onevor more of the slots near the end of the coupling, to allow the band toibe properly adjusted.

The notches or recesses I have au opening into the slot, which just admits the lugs, with a lip, which prevents the removal of the lug when it is in the bottom oi' vthe notch, except by a slight 'longitudinal movement.

This formation of the notch aids in keeping the band J represents lugs, four (more or less in number) ou the outside, atthe center of the coupling, which a'.-

lows, by means of a wrench or otherwise, the coupling to' be held, or prevented from turning, when the nut or band is applied.

It will be seen that, by this arrangement, the suckerrod is inclosed and irmly secured by the coupling.

Having thus described my invention, I claim as new and desire to secure by Letters Iatent- 1'. -The slotted coupling B, the ends of which are contracted, so as to embrace the rod A, by means of a-thimble or nut, and which is provided with the lugs J, substantially in the manner and for the purpose set forth.

2. A sucker-rod coupling, provided with a bayonetclasp catch upon one end, substantially as shown and described.
